TIRE.

Specification of Letters Patent.

Application filed September 15, 1909. Serial No.l 517,814.1l

To all whom 'it may concern:

Be it known that I, DAVID LIPPY, a citi-v zen ofthe United States, residing at Manseld, in the county of Richland and State of Ohio, have invented new and useful Improvements in` Tires; and I do hereby declare that the following is a full, clear,` andexact description of the same.

This invention relates to automobile tires, and more particularly to the armor therefor.

The invention consists in providing a plu-w `rality of plates of different widths arranged in superposed layers, and placed ,edge to v edge, to forma convenient means `for effectually resisting puncture at the tread surace.

The object of the invention is to provide a` plurality of superposed` plates of different widths to resist puncture and varrange them in such manner as to facilitate their assem bling to snugly fit the `continuity of the tire to avoid as much as possible liability* of spacesfor the admission of tacks or the like.

The invention also relates to improvements in the details of construction and arrangement 'of parts, to be hereinafter-described and particularly pointed out in the In the drawings: Figure 1 is a longitudinal section of a tire constructed in accordance with my invention. Fig. 2 is a cross section of the same. Fig. 3 is a similar view,

but showing the tread round `instead of flat' as in Fig. 2. Fig. 4 is a detailperspective view of the armor'. Fig. 5 is'a similar view of a diferent form lof armor.y

1 indicates a tube, which is inflated in the usual manner. On the outer periphery of the tube 1, is located a fibrous band 2, the edges of which are formed -with filling strips 3, designed to support the 'tire parts located adjacent thereto. Interposed between the band 2 and the outer casing-7, is an armor, consisting of two bands 4 and 5, and two layers of metal plates 8 and 9. The metal plates 8 and 9 approximate the width of the tread surfaceof the tire, and are of different width, circumferentiallythereof. The plates 9 are Anarrower than the plates 8, and

liev against the band 5 and are placed edge to edge. the cross sectional width of two of the plates 9, and are placed edge to edge and over the said latter plates 9,' and next to'the band 4.

VOne of theplates 8 is centrally disposed over and secured to one of the plates 9, so that the overlapping ends of said plate 8,

vwill extend over the upper surfaces of the adjacent smaller plates 9 so as to cause the Iassembled series of rows of plates to t snugly the contour ofthe tire surface.-

In Fig. 3 I have shown a slightly diHerent arrangement of the plates, but covering the same generic idea. In this ligure, the inner layer of plates is composed of a series of the wide andrnarrow plates 8 and 9,

yrea-errata Aug. 8,1911.

The wider plates 8 approximate v placed edgeto edge, while the outer or up- '1 per series of plates are arranged in a similar manner. In each instance the wider plates are secured to the narrow plates so that the ends of the wider plates overlap.

The invention is adapted for use with a flat or round tread, and to show such use, I have illustrated the same in Figs'. 2 and 3. In Fig. 2 which shows a flat tread, the band v2 is employed, while in Fig. 3 this filling band is omitted, and between the rounded tread of the casing 7, and the outer band 4, a illing 10 is inserted.

By constructing the armor as described, I eiectually provide a non-puncturable tire. When load pressure is applied'the extreme ends of the plates, by reason of one being of a diii'erent width than the other, they fit closely and practically close the joints.

What I lclaim is:

1. In a tire the combination of a tube, an armor surrounding the outside of the tube, said armor comprising two sets of plates each extending in similar regular order and arranged vin layers one above the other around the circumference of the tire, the plates of each layer being arranged edge to edge and substantially abutting some of the plates being wider than the other plates, and some of the plates of one set overlapping the plates of the other set.

2. A tire comprising a tube, an armor surrounding the tube, said armor consisting of have hereunto subscribed my namev in lthe a set of narrow plates placed edge to edge presence of twowitnesses. and a set of wider plates arranged edge to DAVID LIP?? edge, the wider plates being arranged over f the narrow plates, and `the edges of said Witnesses: wider .plates overlapping said narrow plates.

In testimony that I claim the above, I v SYLVIA BORON.
